I'm not sure why everybody have such a grip on the type.
If I understand the goal of "a new namedtuple" correctly, it is not to come up with yet another namedtuple type -- it is to make the existing collections.namedtuple a faster experience, and possibly add another way to create such a thing.
This means that the "replacement" namedtuple MUST be backwards compatible with the existing collections.namedtuple, and keeping track of type is one of the things it does:
Is it ? Maybe we should check that, cause we may be arguing around a "nice to have" for nothing.
Um, yes, it is. Did you not read the section you snipped? [1]
How many people among those intereted by the proposal have a strong need for the type ?
Whether there is a strong need for it is largely irrelevant; it's there now, it needs to stay. If we were to remove it there would need to be a strong need for what we gain and that it outweighs the broken backward compatibility commitment that we try very hard to maintain. -- ~Ethan~ [1] My apologies for the first paragraph if this is a language translation issue and you were talking about the backwards compatibility and not the type tracking.
